PRESSER-FOOT MECHANISM FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 765,884, dated. July26, 1904.

Application filed $eptember 9, 1901. Serial No. 74,714. (No model.)

To all whom it may concern:

Be it known that I, GARRY J. DoRMANDY, of the city of Troy, county ofRensselaer, and State of New York, have invented new and usefulImprovements in the Presser Foot Mechanism of Sewing-Machines, of whichthe following is a specification.

My invention relates to improvements upon the presser-foot mechanism ofsewingmachines, and more particularly to that class of them in which asupplemental presser-foot is employed in connection with thepresser-foot proper, it being the object and purpose of my invention andimprovements to construct the combined supplemental presser-foot and thepresser-foot proper in such a manner that the latter will be free toautomatically adjust itself vertically to the surface of the materialbeing sewed independently of the supplemental presser-foot and beoperated to rise independently of the latter or in connection therewith.To accomplish these conditions of operation, a jacket is mounted uponthe shank or bar of the presser-foot proper, in which jacket the shankor bar can automatically adjust vertically, with the supplementalpresserfoot slidably and horizontally connected adjustably to saidjacket.

In sewing'collars, cuffs, and other similar apparel-articles it oftenbecomes desirable after stitching the edges of an article being sewed torun another line of stitching inside of that formed upon the edge andnearer to the horizontal center of the article, which operation asheretofore employed required a change of the attachable and detachableparts of the machine and which operation can be done without this delayby using the supplemental foot of my machine as a gage for the border oredge stitching and as a presser-foot for the stitching done inconnection with the presser-foot proper.

In the stitching of a collar body and band and the connection of thelatter tothe former the supplemental presser-foot of myinvention becomesa very useful appliance in' the fact that it adapts the same machine toperform both operations and in sequence.

Accompanying this specification to form a part of it there are fourplates of drawings, 5 containing eleven figures, illustrating theapplication of my invention, with the same designation of parts byletter reference used in all of them.

Of the illustrations, Figure l is a perspective of that part of thefront end of a sewingmachine arm in which the presser-foot proper andthe needle-bar are located and operated,

my improvement being shown as applied thereto and as having thesupplemental foot thereof employed as a gage. Fig. 2 is a perspective ofthe same parts that are illustrated at Fig. 1, but shown with thesupplemental foot used as a presser-foot. Fig. 3 is an end elevation ofthe machine. Fig. 4 is an en- 5 larged front end elevation of thepresser-foot proper, the vertical bar on which it is operated, and themechanism by which the supplemental foot is connected thereto. Fig. 5 isan elevation of the rear of the presser-foot '7 proper, the supplementalfoot, and its connection, illustrating a pivoted cam whereby the jacketin which the supplemental foot is mo unted, as shown by a dotted line,is caused to engage with the stock of the presser-foot proper, so as torise together, with the supplemental foot shown as resting upon thetable. Fig. 6

is a front view of the parts shown at Fig. 5. Fig. 7 is aperspective ofthe jacket in which the supplemental foot is mounted illustrated asdetached. Fig. 8 is a perspective of the supplemental foot shown asdetached, with its position when moved laterally on its mounting in thejacket designated by a dottedline. Fig. 9 is a perspective of thepresser-foot 5 proper shown as detached. Fig. 10 is a perspective of astop-plate that is adapted to adjustably connect to the stock with whichthe vertical bar of the presser-foot proper is mounted. Fig. 11 is'afront end view of a 9 sewin -machine containing my invention with the mrk anism operating the presser-foot proper an the supplemental presserfoot when connected to rise and descend together, this mechanism .beingshown in part in full lines and in parlr by' dotted lines, with thefront wall of the machine-arm in which lo cated illustrated ascut awayin part.

its connected presser-foot proper, together with the supplemental foot,at the same time this cam-lever is swung inwardly on its pivotalconnection until its upper end 6 is in contact engagement with the underside of the jacket-top j at 0 with the parts appearing as shown by thedotted line 1 at Fig. 5. The letter G designates a gage that isadjustably connected to the table-plate of the machine by means ofthumb-screw U and the slot V, formed in the gage-plate. Thus constructedwhen the lever L is operated to raisethe bar B and the presser-footproper, as before described, it can be so actuated as to raise thelatter independently of the jacket and the supplemental presser-foot,and with the camlever C of the stock S actuated to engage with the top jof the jacket the latter, the supplemental presser-foot, andpresser-foot proper may be raised together, with thecamlever O in theposition shown by the dotted line at Fig. 5. Vith the supplemental footthus free to adjust on the stock of the presserfoot proper it isrelieved from the upthrow tendency given to the latter by the feedmechanism, and this uniformly steady position of the supplementalpresser-foot is manifested equally well when it is used as a gage, thusdifi'ering materially from the older trip-gages, which are attached tothe presser-foot proper and subject to the same upthrow tendency andvibration produced by the feed mechanism.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a sewing-machine, the combination, with the presser-foot proper,the bar thereof provided with a stock supporting the presserfoot, andmeans for raising or lowering said parts, of the jacket verticallymovable upon the stock, a horizontally-arranged supplementalpresser-foot adjustably connected to said jacket to move laterally, anda locking device mounted on the stock for connecting the presser-footproper and the supplemental presser-foot to rise together, forsubstantially the purposes set forth.

2. In a sewing-machine, the combination with a presser-foot propermounted upon the lower end of a bar vertically movable in the dependingarm of the sewing-machine, and provided with means whereby it may beraised and lowered, of a stock which is rectangular in cross-sectionmounted upon said bar to move with it, a jacket having an overhangingtop provided with a vertical passage for said bar, and the jacket-bodyhaving a free rectangular passage for said stock, a supplementalhorizontally-arranged presser-foot adjustably connected to one of thejacket sides, a spiral spring encircling said bar between the top of thejacket and the bottom of the sewing-machine arm, whereby said jacket andsupplemental presser-foot will bear steadily upon work in a desiredalinement independently of the vibration of the presser-foot proper, forsubstantially the purposes set forth.
